FREE!! Unknown vacuum pumps

So I have these two vacuum pumps that were removed from our shop's air conditioning recovery machines years ago (unknown what brand the machines were) and I can't find any info online it seems. Do the labels give any indications that they'd be suitable? Also, there's four wires...likely two power wires and two switch wires?

I'm not into composites at all, but want to try some small vacuum bagging items like servo covers and canopies, etc, and if they're strong enough, to use with plastic sheet vacuum forming as my tiny shop vac doesn't work too well.

Anybody local to SF Bay Area want these two pumps for free?
I really don't intend to ever do vacuum bagging after all, and they've been sitting in the cabinet untouched since getting them.
They're very heavy and I won't ship 'em...hence FREE!
